A system for converting solar energy into electric energy characterized in that it comprises at least three photovoltaic panels (1) arranged outside a building, a radial flow supply-exhaust fan (2), an air turbine (3) with at least three blades (8), a multiplying gear (5) and a synchronous generator (6).

Description

Solar-air home mini power plant
The subject of this invention is a system for converting solar energy into electric energy, particularly in small households.
Technical solutions of generating electric energy are known from prior art. The Polish patent specification PL207540 describes a hydroelectric power plant for generating electric energy by converting the energy of water flow by means of a fluid-flow machine having at least one rotor, a generator driven by the said rotor, and a float for the fluid-flow machine, wherein the fluid-flow machine is anchored to a rock, and the rotor is oriented in the direction of the flow. The Polish patent application P-372240 discloses a method of electric energy generation from low- grade waste heat / solar energy, wherein use is made of a closed-cycle refrigerant loop. A refrigerant fluid is pumped under pressure and at ambient temperature through a heat exchanger (14) connected to a source of waste heat / solar energy, and subsequently generates thermal energy during its conversion to a high pressure gas. The heated / pressurized refrigerant gas is fed to an expander (20) to drive an output shaft (26) as a result of expanding the fluid to a cooled gas at approximately 0 psig. The cooled gaseous refrigerant is condensed to a liquid at low pressure and ambient temperature, and recycled under pressure to the heat exchanger. The expander is a reverse-plumbed gas compressor: the pressurized refrigerant gas is inlet at what is ordinarily its outlet, whereas the normal inlet becomes the expander end. The refrigerant gas mass flow pressure/temperature drop spins the expander shaft, enabling direct mechanical power take-off, or upon coupling to a synchronous or inductive generator it is used to produce electricity.
The purpose of the present invention is to generate electric current for captive use in a household. panels arranged outside a building, a radial flow supply-exhaust fan, an air turbine with at least three blades, a multiplying gear and a synchronous generator. Preferably the photovoltaic panels are arranged on the roof of the building. Preferably the photovoltaic panels are arranged on the wall of the building.
The photovoltaic panels arranged outside the building, preferably on the roof or on the wall of the building, generate electric energy which is stored in gel batteries.
The radial flow supply-exhaust fan, arranged inside the building, is powered by electric energy generated by the photovoltaic panels. The air turbine has a rotor with at least three blades. Preferably the diameter of the rotor is between 0.5 and 1.5 m.
The radial flow supply-exhaust fan generates a stream of air with a velocity of 15 to 30 m/s, which drives the air turbine rotor 0.5 to 1.5 m in diameter, the shaft of which transfers power, torque and rotation via elastic couplings and multiplying gears onto the shaft of the low-speed synchronous generator. Electric energy from the synchronous generator is drawn by external consumers.
The outside air drawn in by the fan, upon passing through the air turbine, is expelled outside the building. During the summer season the outlet air may be used inside the building as ventilation air.
The system according to the invention enables the utilization of solar energy under household conditions to generate electric energy in quantities sufficient for captive use, with any surplus energy sellable on the free market. The use of the photovoltaic power supply makes the system independent of any additional external installations.
An example of embodiment of the subject of the invention is presented in drawings, wherein Fig. 1 shows the system for converting solar energy into electric energy, and Fig. 2 shows the air turbine used in the system.
EXAMPLE
The system comprises three photovoltaic panels 1 with an output of 240W arranged on the roof of the building, a radial flow supply-exhaust fan 2, an air turbine 3, elastic couplings 4, a multiplying gear 5 and a synchronous generator 6. The air turbine 3 consists of a polypropylene rotor 7 with three blades 8. The diameter of the gel batteries. The fan 2, powered by electric energy generated by the photovoltaic panels 1, generates a stream of air with a velocity of 15 to 30 m/s for the turbine 3. The stream of air generated by fan 2 drives the rotor 7 of turbine 3, the shaft of the latter transfers power, torque and rotation via elastic couplings 4 and multiplying gear 4 onto the shaft of the low-speed synchronous generator 6. Electric energy from the synchronous generator 6 is drawn by external consumers. The synchronous generator 6 generates electric energy during daytime and after dusk until the batteries run flat.
